which will minimize the socket impedance.
When using a through hole socket, the vias un-
der the codec in Figure 19 are not needed since
the pins serve the same function.
ADC and DAC Filter Response Plots
Figures 21 - 26 shows the overall frequency re-
sponse, passband ripple and transition band for
the CS4216 ADCs and DACs. Figure 27 shows
the DACs’ deviation from linear phase.
Fs is defined as the selected sample frequency
and is also the SSYNC frequency. Since the
sample frequency is programmable, the filters
will adjust to the selected sample frequency.
